What the filename identifies
SequoiaDenso identifies the vehicle name and controller supplier in the catalog. The related entry 89663-0C202 matches the calibration identifier in the filename. The TUN E2 suffix labels this file as a tune variant, but the catalog name does not establish which settings were changed or what effect those changes have on driving.
The filename alone does not establish an exact model year, engine application or interchangeability with another calibration. It also does not document a particular factory revision or a stock counterpart.
